LIQUID-DISPENSING DEVICE.

Application filed November 4, 1924. Serial No. 747,878.

To all ifi/0m t may concern:

Be it known that I, WILLIAM H. Rose, a citizen yof the United States,residing at Jersey City, county of `Hudson, and State of New Jersey,have invented new and useful Improvements in Liquid-Dispensing Devices,of which the following is a full, clear, and exact specification.

My invention relates to liquid dispensing` devices and refersparticularly to devices of this character of a construction particularlyadapted for use with disinfectants.

1t is frequently desirable to employ disinfectants in small. quantitiesat predetermined periods, the delivery of the disinfectant from areceptacle being Acaused either automatically or through manualmanipulation.

The present employed methods for accomplishing these results by means ofabsorbent wicks is not applicable to many disinfectants, because of theabsence of proper capillary power of the wick, or because of the eiectof the solution upon the wick, causing the delivery of the liquid to beuncertain or entirely interrupted.

Devices of the wick character can not be employed with soluble soapdisinfectants, which rapidly decrease the capillary properties of thewick with the resultant discontinuance of disinfectant delivery.

My device overcomes these, and other, objectionable features of thepresent employed devices and 4presents armeans whereby disinfectants ofthe soluble soap class, and others, may be successfully applied.

My device includes a particularly formed valve, or valves, of suchconstruction as to retain the liquid within the receptacle when it isnot in operation, but will allow of the escape of the liquid inquantities dependent upon the amount and duration of pressure applied tothe liquid within the receptacle.

1t is immaterial in the employment yof my device as to the source ofpressure, which may be of manual, mechanicahelectric, or other types, asthe device may be regulated to operate successfully by any means whichwill allow of interrupted pressure upon the receptacle contents.

The obj ect of my invention, therefore, is a liquid dispenser withoutwicks, or other elements depending upon capillary attraction, capable ofthe intermittent delivery of small quantities of liquids from areceptacle, the

delivery being` caused by pressure upon lthe. liquid within thereceptacle, the device being applicable to soluble disinfectants of thesoluble soap and other types of chemicals.

ln the accompanyinpr drawings illustrating modified forms of the deviceif my iuvention, similar parts are designated by similar numerals.

Figure 1 is a view of one forni of my device showing one means of itsattachment to a supply receptacle.

Figure 2 is a broken vertical cross-section of one form of my device.

Figure 3 is a broken vertical cross-section of a modified form of mydevice.

Figure 4 is a broken vertical cross-section of a modified form of mydevice showing means for attaching and retaining the disc valve member.

Figure 5 is a verticalv cross-section showing a modified form ofpressure means.

The particular form of the device of my invention, shown in Figures 1and 2, comprises an annular receptacle having the top 10 and the side11. The side 11 carries the inwardly extended flange 12 thus forming anopening 13. The lower portion of the inner face of the side 11 isinternally threaded to mesh with an externally threaded ring 14. Thering 14 and the flange 12 thus act as a support for the rubber disc 15,producing a tight liointure. The disc 15 has a centrally positionedincision, or slot, 16, which remains closed under normal conditions butwhich may be opened to release liquid from within the receptacle whenpressure is exerted upon said liquid.

A tube 17 is threaded within the threaded opening 18 of the top 10 andis connected to the tube, or pipe, 19 by means of the coupling 20, thetube 19 being connected to a supply receptacle 21, which need not behermetically sealed by the lid 22. A tube 23 is threaded within athreaded opening of the receptacle and is connected to the pipe 24 bymeans of the coupling' 25. The tube 24 is attached to the base plate 25,to which is attached the semi-spherical rubber pressure member 26 bymeans of the binding wire 27.

Within the tube 17 is a flap valve member 28 having the incision 29forming a flap valve 30, the valve allowing the downward iow of liquidfrom the pipe 17 when in normal position but being closed when pressureis exerted upon the under tace oit the flange valve 30.

In ope ation, the supply receptacle .contains a liquid which flowsdownwardly through the pipe members illing the receptacle, the valvedisc l5 preventing` the liquid from passing therethrough. It the rubbermember 26 be pressed, a pressure will be produced upon theliquid in thereceptacle causing the flap valve 30 to close and the incision valveopening 1G to open, allowing the escape ot' liquid from the receptacle.

The design illustrated in Figure 3 is similar in construction to thatdescribed above, with the exception that the flap valve is omitted fromthe pipe 17 and the supply receptacle 2l is closed and air-tight. Itwill thus be seen that a pressure upon a rubber pressure memberconnected to the pipe 24 will cause the incision valve l5 to open andallow of the escape oil liquid from the receptacle.

In the device shown in Figure e, the valve disc 15 is retained in placeby the angular member 3l threaded upon the outer face ot' the receptacleside l1 and having an opening 32 therein.

Figure 5 illustrates a convenient an'd etlicient pressurebulb,comprisingthe base 32 and the cap 33 having an opening 34 there`in, a hollow rubber member 35 rests upon the base 32 and has its pushbutton 36 extended through the Vopening 34. VThe parts thereof may be sointerrelated that the downward pressure of theinember 36 unt-il it isflush with the cap 33 will cause the release of a required quantity ofliquid from the receptacle. j

I do not limit myself to the particular size, shape, number, orarrangement of parts, as shown Vand described, as ythese are givensimply as a means for clearly describing the device of my invention.
